   Areas affected...southeast Georgia

   Concerning...Tornado Watch 140...

   Valid 231725Z - 231900Z

   The severe weather threat for Tornado Watch 140 continues.

   SUMMARY...Threat for tornadoes, some strong, and damaging wind will
   persist across southeast GA through 19Z.

   DISCUSSION...A progressive bow echo with embedded supercell
   structures continues moving eastward through southern GA at around
   45 kt, and will reach the coast around 1930Z. A warm front has been
   advancing northward, and this activity will likely move along this
   boundary during the next couple hours. The atmosphere remains
   modestly unstable with 500-1000 J/kg MLCAPE along with large 0-1 km
   hodographs with 200-400 m2/s2 storm relative helicity. Tornadoes and
   damaging wind will remain likely as this storm moves east through a
   favorable environment and interacts with the warm front.
